Hi Roman,
I just got your sample working (against SVN trunk) by changing the code
to unmarshal things to:
XMLContext context = new XMLContext();
context.addPackage("your.package");
Unmarshaller unmarshaller = context.createUnmarshaller();
Reader source = new FileReader(exampleXml);
Object object = unmarshaller.unmarshal(source);
I hope this helps.
Regards
Werner
